ACTION KendallC: put xml format up somewhere public, mail a pointer
done: http://lists.w3.org/Archives/Public/public-rdf-dawg/2004JulSep/0554.html
ACTION DaveB: draft XML query results format spec.
done: http://lists.w3.org/Archives/Public/public-rdf-dawg/2004JulSep/0556.html
Discussion of this format and tradeoffs. Missing bits included XML
literal example, empty literal vs missing binding. Further
discussion of blank nodes in results and possible issue of
constraining variable names to be XML happy; they already are in rq23
grammar (XML NCName).
It was noted this was one of two result formats - variable bindings
and rdf graphs. The latter have a recommended syntax RDF/XML and
others that also can be used. Need a format for the former - this
action, however it was requested that this might be returned as RDF
triples, like the RDF schema for the query test results. CONSTRUCT
only returns graphs. ASK returns a boolean, and also should have a
format YES/NO, 1/0 for use without a protocol.
ACTION EricP: follow up on " if we send a query to the document
rather than service, we loose some of the document compositibility
possibilities" in email (from http://w3.org/2004/09/17-dawg-irc)
CONTINUED
ACTION KendallC: write a protocol document draft (est delivery in 1
month).
Work proceeding on this but not yet ready for review.
